ACOM CM-10 Antenna Crank-up Mast

Do not work alone! At least one helper must be engaged in the processes to provide mutual aid in

case of hazardous situations. If you have doubts concerning the safety, please consult your dealer or

engage a professional company for installation of your mast.

Prior to mast assembly, the site must be rendered safe and marked.

Use the needed personal safety means while installing the antenna mast.

Location

The antenna mast must be located in the clear, away from trees, power installations, buildings, other

masts, antennas etc. Such objects can be dangerous and they can reduce the antenna efficiency or

cause interference.

Your first steps

The first step to installation is to fully read this manual. Then, carefully inspect the shipping cartons for

any physical damage. ACOM ships antenna masts in highly protected containers, but it cannot assure

that mistreatment by shippers will not occur. If there is any such damage, notify your ACOM dealer

immediately. Failure to do so may invalidate your warranty.

The ACOM production uses metric (European) system of measuring units. Make sure that you have

got all necessary tools, such as sets of wrenches, screwdrivers, pliers etc. and they are in good shape.

2. ASSEMBLING.

An overall view of the antenna mast is shown in Fig.1.

For the installation, the site must be marked according to Fig.1. On the spots shown, strong supporting

anchor points of high grade materials must be provided for fixing the framework base and mast guy

ropes.

During installation all mechanical joints must be tightened securely with appropriate tools.

While lifting the mast with antenna attached to its top, the guy ropes should be stretched

simultaneously so that the mast is not put to lateral pressures.

Assembly and lifting sequence

Place the mast framework on the preliminary prepared foundation consistent with framework's base

(Fig. 1), and make sure that it is vertical by means of a plumb line. Provide four anchor points for

framework's guy ropes (minimum 1.25 m from base center).

Attach the framework guy ropes to the upper framework plate and to the respective anchor points;

stretch them tight and evenly by means of the turnbuckles (Fig.2).

After the framework is fixed firmly, attach to it the hand winch, upper pulley and lifter. Fix the rope to

the hand winch following the winch instructions (supplied with mast) and pass it in the way as shown.

Tighten the thread end to the middle framework plate using a washer and nut M8.

Place tube marked No10 (it will be mast's uppermost segment) into the framework's apertures and

secure it with the supporting pin (Fig. 3). Mount on it the guy rope straps, mast tip, fixing bushing and

relevant mounting hardware, as shown in Fig.3. Bolt M10x100 must pass through tube No10 and the

hole at the tip. In such a way the tip is secured against turning.

Place the next tube (No 9) under the first one so that the lifter's fixing pin gets into the tube's fixing hole of

tube No 10 (Fig. 4). In the same manner orientate the two tubes toward the lifter. After they are aligned,
